Hi qayyumfaiz
Without having the correct programming software and cable there is not much chance to see anything.
You can choose whether CPU will restart automatically after a reboot or not.
If you can't start it via buttons, the chance is good that there is no application loaded.
You could ask supplier to provide a printout of the loaded application and ask whether automatic restart of CPU after power recovery has been activated or not, but this should also be visible from print out.
